High fill slope drainage structure and construction method thereof
The invention relates to the technical field of slope drainage engineering, and discloses a high fill slope drainage structure. The high fill slope drainage structure comprises a shallow drainage blind ditch and a deep drainage blind ditch which are arranged in a high fill slope, wherein the shallow drainage blind ditch extends into a slope body by a certain depth from the slope surface; the deep drainage blind ditch is arranged at the bottom of the high fill slope; the peripheries of the drainage blind ditches are wrapped with geotechnical cloth; cushion layers, reinforced concrete pipes and gravels are arranged in the drainage blind ditches; the cushion layers are arranged at the bottoms of the drainage blind ditches; the reinforced concrete pipes are arranged above the cushion layers; a plurality of water inlets are formed in the upper half parts of the reinforced concrete pipes; and the outer sides of the reinforced concrete pipes are filled with the gravels. Through the arrangement of the shallow drainage blind ditch and the deep drainage blind ditch to form a blind ditch drainage system, and through a mode of guiding and draining underground water in the slope body, the problem of poor drainage effect of the deep drainage blind ditch when more underground water permeates into the slope body from the ground surface is solved; and through the arrangement of the reinforced concrete pipes, the problems of poorer compressive property, easiness in damage and poorer durability of a traditional plastic blind pipe are solved.
本发明涉及坡体排水工程的技术领域，公开了填土高边坡排水结构，包括布置于填土高边坡内部的浅层排水盲沟和深层排水盲沟，浅层排水盲沟从坡面伸入坡体一定深度；深层排水盲沟设于填土高边坡的底部；排水盲沟的外周包裹有土工布，排水盲沟内设有垫层、钢筋混凝土管和碎石，垫层设于排水盲沟的沟底，钢筋混凝土管设于垫层的上方，钢筋混凝土管的上半部开设有多个进水孔，碎石充填在钢筋混凝土管的外侧。通过布置浅层排水盲沟、深层排水盲沟组成盲沟排水系统，导排坡体内部地下水的方式，解决了从地表渗入到坡体内部的地下水较多时，深层排水盲沟排水效果差的问题；钢筋混凝土管的设置，克服了传统塑料盲管抗压性能较差、易损坏、耐久性较差的问题。
